Seasonality score systems and methods

ABSTRACT

Systems and methods for generating and using seasonal affinity scores is disclosed. A set of user-specific historical transaction data is obtained and a user-specific affinity score including at least one of a user-specific season affinity score or a user-specific seasonal theme affinity score is determined by determining one or more product affinity scores for a set of product taxonomies and combining the one or more product affinity scores with one or more product index scores to generate the user-specific affinity score. The product affinity scores are determined by a trained scoring calculation model configured to receive the set of user-specific historical transaction data. One or more interface elements are selected based on the user-specific affinity score and an interface is generated including the one or more interface elements.

TECHNICAL FIELD

This application relates generally to data retrieval and, more particularly, to machine-learnt retrieval using seasonality scores.

BACKGROUND

Computer-implemented retrieval of relevant items from a database or catalog relies on item scoring. Current systems utilize scoring functions that consider past item selection history to identify and present preferred items through an interface. For example, in an e-commerce environment, a scoring function may identify products for presentation through an e-commerce interface based on prior product selection and attributes, such as brand, product type, size, product category, etc.

Over a given time period (such as a calendar year), user preferences may change based on specific holidays, festivals, events, etc. (referred to herein as “seasons”). Current systems utilize item selection (e.g., purchase) histories without accounting for user preference changes due to changing seasons. In addition, while some users may have a seasonal preference related to a first season, other users may have a seasonal preference related to a second season that overlaps with the first season.

SUMMARY

In various embodiments, a system is disclosed. The system includes a non-transitory memory having instructions stored thereon and a processor configured to read the instructions. The processor is configured to obtain a set of user-specific historical transaction data, determine a user-specific affinity score including at least one of a user-specific season affinity score or a user-specific seasonal theme affinity score, select one or more interface elements based on the user-specific affinity score, and generate an interface including the one or more interface elements. The user-specific affinity score is determined by determining one or more product affinity scores for a set of product taxonomies and combining the one or more product affinity scores with one or more product index scores to generate the user-specific affinity score. The product affinity scores are determined by a trained scoring calculation model configured to receive the set of user-specific historical transaction data.

In various embodiments, a non-transitory computer readable medium having instructions stored thereon is disclosed. The instructions, when executed by a processor cause a device to perform operations including obtaining a set of historical transaction data, determining an affinity score including at least one of a season affinity score or a seasonal theme affinity score, selecting one or more interface elements based on the affinity score, and generating an interface including the one or more interface elements. The affinity score is determined by determining one or more product affinity scores for a set of product taxonomies and combining the one or more product affinity scores with one or more product index scores to generate the affinity score. The product affinity scores are determined by a trained scoring calculation model configured to receive the set of user-specific historical transaction data.

In various embodiments, a computer-implemented method is disclosed. The computer-implemented method includes the steps of determining one or more product affinity scores for a set of product taxonomies, combining the one or more product affinity scores with one or more product index scores to generate a user-specific affinity score, selecting one or more interface elements based on the user-specific affinity score, and generating an interface including the one or more interface elements. The product affinity scores are determined by a trained scoring calculation model configured to receive a set of historical transaction data.

FIG. 2 illustrates a network environment 20 configured to provide item recommendations and suggestions based on a user season affinity score and/or one or more user theme affinity scores, in accordance with some embodiments. The network environment 20 may include, but is not limited to, one or more user systems 22 a, 22 b, a network interface system 24, an element selection system 26, an affinity score calculation system 28, a model training system 30, one or more item databases 32 a, 32 b, one or more historical transaction databases 34, and/or any other suitable system. Each of the systems 22 a-30 and/or the databases 32 a-34 may include a system as described above with respect to FIG. 1 . Although embodiments are illustrated herein having discrete systems, it will be appreciated that one or more of the illustrated systems may be combined into a single system configured to implement the functionality and/or services of each of the combined systems. For example, although embodiments are illustrated and discussed herein including each of a network interface system 24, an element selection system 26, a affinity score calculation system 28, and a model training system 30, it will be appreciated that these systems may be combined into a single logical and/or physical system configured to perform the functions and/or provide services associated with each of the individual systems. It will also be appreciated that each of the illustrated systems may be replicated and/or split into multiple systems configured to perform similar functions and/or parts of a function.

In some embodiments, the network interface system 24 is configured to provide a network interface to the one or more user systems 22 a, 22 b. The network interface may include any suitable type of network interface, such as, for example, an e-commerce interface, a search interface, an inventory interface, etc. Although embodiments are discussed herein with reference to an e-commerce network interface, it will be appreciated that the disclosed systems and methods are applicable to any interface including sets of items that may be associated with various seasons and/or themes.

In some embodiments, the network interface 24 is configured to receive a user identifier from a user system 22 a, 22 b. The user identifier may include, for example, a user name, an identifier included in a cookie or other digital file, and/or any other suitable identifier. The identifier is unique to a user and/or may identify a user system 22 a, 22 b used by multiple users.

In some embodiments, the network interface system 24 is in signal (e.g., data) communication with an element selection system 26. The element selection system 26 is configured to retrieve a set of items for inclusion in the user interface based on a user season affinity score and/or one or more user theme affinity scores. For example, in some embodiments, the element selection system 26 utilizes a calculated user season affinity score to select items associated with a predetermined season. As another example, in some embodiments, the element selection system 26 utilizes one or more calculated theme affinity scores to select items associated with one or more predetermined seasonal themes. The selected items may be presented to a user through the user interface, for example, as a container element presented in one or more containers within the user interface (e.g., lists, carousels, etc.).

In some embodiments, the element selection system 26 is in signal (e.g., data) communication with one or more item databases 30 a, 30 b containing data elements corresponding to items available in one or more catalog of items. In some embodiments, the element selection system 26 is configured identify items within the one or more item databases 32 a, 32 b based on user season affinity scores and/or user theme affinity scores. For example, in some embodiments, the items stored and/or represented within each of the one or more item databases 32 a, 32 b may include identifiers associating the items with one or more seasons and/or one or more seasonal themes. The element selection system 26 may be configured to retrieve items that are categorized and/or otherwise associated with seasons or seasonal themes for which a user has a high affinity, e.g., for which the use has a high affinity score, as discussed in greater detail herein.

In some embodiments, the element selection system 26 is in signal (e.g., data) communication with a affinity score calculation system 28. The affinity score calculation system 28 is configured to calculate a user season affinity score and/or one or more user theme affinity scores for the user. As discussed in greater detail below, the affinity score calculation system 28 is configured to utilize historic transaction data in conjunction with one or more trained machine learning models to calculate a user-specific affinity score for one or more seasons and/or one or more seasonal themes.

As used herein, the term “season” refers to events, holidays, activities, festivals, etc. that occur within a common temporal period within a specific time frame. Examples of seasons may include, but are not limited to, yearly holidays or festivals occurring on specific days (such as New Year's Day, Fourth of July, Juneteenth, Christmas, etc.), yearly holidays or festivals occurring over multiple days (e.g., Hanukah, Kwanza), and/or any other suitable reoccurring activity or event within a temporal period.

In some embodiments, the term season refers to a portion of time leading up, surrounding, and/or following a holiday, event, etc. (e.g., “Christmas Season,” “Holiday Season,” “Valentine's Season,” etc.). In some embodiments, the term season refers to periods of time related to specific themes or activities that are common during a period of the year (or other temporal identifier). For example, such seasons may coincide with activities common to predetermined time periods during a temporal period, such as a calendar year (e.g., “Beach Season,” “Ski Season,” “Back to School Season,” etc.). As another example, such seasons may coincide with actual seasons defined by temporal periods (e.g., “Summer season,” “Fall season,” etc.). It will be appreciated that a “season” may refer to any specific temporal period that includes common elements, items, etc.

In some embodiments, each season includes one or more “themes.” For example, in various embodiments, themes may include, but are not limited to, activities performed during the season, items purchased during the season, sentiments or ideas common to the season, and/or any other common concept, idea, or other theme of the defined season. As one non-limiting example, a “Holiday Season” may be defined that includes various “Holiday” related themes, such as, for example, a “holiday lighting” theme, a “holiday present” theme, a “holiday dinner” theme, a “holiday activity” theme, etc. Each of the themes may similarly include sub-themes. For example, the “holiday present” theme of the prior example may include various categories such as “Infant presents,” “toddler presents,” etc. As will be appreciated, the various season and/or themes may be broadly and/or narrowly defined to allow focus on various sets of goods, services, items, etc. that may be presented by the user interface.

In some embodiments, the affinity score calculation system 28 is configured to generate seasonal affinity scores and/or theme affinity scores for a user associated with the user system 22 a, 22 b. For example, in some embodiments, the affinity score calculation system 28 implements a trained machine learning model configured to calculate a user seasonal affinity score based on historical data. The historical data is stored in a database, such as historical database 34, in signal communication with the affinity score calculation system 28. The affinity score calculation system 28 retrieves historical data for a user associated with the user system 22 a, 22 b and, as discussed in greater detail below, provides the historical data to at least one trained machine learning model configured to calculate a user seasonal affinity score and/or one or more user theme affinity scores.

In some embodiments, the affinity score calculation system 28 is in signal (e.g., data) communication with a model training system 30. The model training system 30 is configured to generate and/or update one or more trained machine learning models configured to calculate a seasonal affinity score and/or a theme affinity score. In some embodiments, the model training system 30 is configured to implement a machine learning process based on historical data for a large customer base. As discussed in greater detail below, the model training system 30 may be configured to generate a trained alternating least square (ALS) model, although it will be appreciated that any suitable machine learning model and/or architecture may be used.

FIG. 3 is a flowchart illustrating a method 100 of generating a network interface including elements selected based on one or more seasonal affinity scores and/or one or more theme affinity scores, in accordance with some embodiments. FIG. 4 is a process flow 150 illustrating various steps of the method 100 of generating a network interface illustrated in FIG. 3 , in accordance with some embodiments. At step 102, a user identifier 152 is received by a network interface system, such as, for example, the network interface system 24 discussed above. As previously discussed, the network interface system 24 is configured to generate one or more network environments or interfaces. Embodiments discussed herein include an e-commerce environment, although it will be appreciated that other environments, such as development environments, service environments, etc., may be provided by the network interface system 24.

The user identifier 152 is configured to identify a user associated with a user system 22 a, 22 b. The user identifier 152 may include any suitable user identifier, such as, for example, a user name, a unique token or identifier, a beacon code, a cookie identifier, etc. The user identifier 152 may be automatically provided by a user system 22 a, 22 b when the user system 22 a, 22 b interacts with the network interface system 24 and/or may be provided by a user of the user system 22 a, 22 b when prompted, for example, through a website log-in or other user interface element.

At step 104, the user identifier 152 is used to obtain a user-specific seasonal affinity score 154 and one or more user-specific seasonal theme affinity scores 156 a-156 c. The user-specific seasonal affinity score 154 and/or the one or more user-specific seasonal theme affinity scores 156 a-156 c may be received from an affinity score calculation system 26. As discussed in greater detail below, the user-specific seasonal affinity score 154 and/or the one or more user-specific seasonal theme affinity scores 156 a-156 c may be calculated using one or more trained machine learning models configured to calculated seasonal affinity and/or theme affinity scores. The user-specific seasonal affinity score 154 and/or the one or more user-specific seasonal theme affinity scores 156 a-156 c may be pre-calculated for a user and/or may be calculated in “real-time” when a user interacts with a network interface system 24. In some embodiments, the user-specific seasonal affinity score 154 and/or the one or more user-specific seasonal theme affinity scores 156 a-156 c are represented by a number between 0 and 1, although it will be appreciated that any suitable range and/or representation may be used.

Each of the user-specific seasonal affinity score 154 and/or the one or more user-specific seasonal theme affinity scores 156 a-156 c identify a user affinity, or preference, for one or more selected seasons. A user-specific seasonal affinity score 154 above a selected threshold indicates that a user has an affinity, or preference, for a season. For example, a user-specific seasonal affinity score above a selected threshold for a “Valentine Season” illustrates a strong user preference for the Valentine's Day holiday. With respect to an e-commerce environment, a user-specific seasonal affinity score 154 above a selected threshold represents a likelihood that the user will purchase goods and services that are associated with the season. For example, continuing the “Valentine's Day” season example, a user having a user-specific season affinity score 154 above a selected threshold for “Valentine's Day” is more likely to purchase Valentine's Day themed decorations, presents, candies, etc., as compared to a baseline consumer. Conversely, a user-specific seasonal affinity score 154 below a selected threshold indicates a lack of interest or interaction with a specific season, and thus a lower likelihood of a user purchasing seasonal-themed products.

Similarly, a user-specific season theme affinity score 156 a-156 c above a selected threshold indicates a user preference for specific themes within a season. A season may include various themes such as, for example, “Seasonal decorations,” “Seasonal foods,” “Seasonal décor,” “Seasonal candy,” etc. A user may have a high affinity for one or more season-specific themes while having a low affinity for one or more other season-specific themes. As one non-limiting example, a user may have a “Halloween Candy” seasonal theme affinity score above a selected threshold and a “Halloween Decoration” seasonal theme affinity score below a selected threshold, indicating a preference for buying Halloween candy but not Halloween decorations.

At step 106, user-specific seasonal affinity score 154 and/or the one or more user-specific seasonal theme affinity scores 156 a-156 c are used to generate item and/or element recommendations for populating one or more user interface and/or network environment elements. For example, if a user has a user-specific seasonal affinity score 154 above a selected threshold for an active season, the element selection system 26 selects elements and/or items for presentation in the user interface from elements or products labeled as being associated with the active season. Similarly, if a user has one or more user-specific seasonal theme affinity scores 156 a-156 c above a selected threshold for an active season, the element selection system 26 selects elements and/or items for presentation identifies as being associated with the specific seasonal theme. Alternatively, in some embodiments, the element selection system 26 is configured to select generic elements and/or items for presentation when each of the relevant season affinity scores and/or theme affinity scores are below selected thresholds for active seasons.

The threshold used for identifying a user affinity with a specific season and/or specific theme may vary based on one or more factors. For example, in some embodiments, a threshold set for a season may be higher or lower depending on the regional popularity and/or observance of a specific season. Similarly, in some embodiments, a threshold for a seasonal theme may be higher and/or lower depending on the number of products associated with a theme. It will be appreciated that any suitable factors may be used to set seasonal and/or theme affinity thresholds.

Elements and/or items may be selected by the element selection system 26 using any suitable element selection process. For example, in some embodiments, the element selection system 26 implements an element selection process as described in U.S. Pat. Appl. No. 17,096,666, filed Nov. 12, 2020, entitled “Systems and Methods for Personalized Complementary Recommendations,” the disclosure of which is incorporated herein by reference in its entirety.

At step 108, a network interface 160 is provided to the user system 22 a, 22 b including user-affinity elements 162 selected based on user-specific seasonal affinity score 154 and/or the one or more user-specific seasonal theme affinity scores 156 a-156 c. The network interface 160 may include user-affinity elements 162 (e.g., items, images, etc.) associated with one or more active seasons for which the user-specific seasonal affinity score 154 and/or the one or more user-specific seasonal theme affinity scores 156 a-156 c is above a selected threshold. Similarly, the network interface 160 may include generic elements 164 when the user-specific seasonal affinity score 154 and/or the one or more user-specific seasonal theme affinity scores 156 a-156 c are below a selected threshold for each of the active seasons.

Although embodiments are discussed herein including generation of a network interface, it will be appreciated that the seasonal affinity and/or seasonal theme affinity scores discussed below may be used for any suitable purpose. For example, in some embodiments, seasonal affinity and/or seasonal theme affinity scores may be calculated for a set of users to predict user demand for certain products or processes during a season. The prediction of user demand may be used, for example, to assist in logistical preparation for the season including stocking of various products, distribution of products, sales and marketing, and/or any other suitable logistical preparation based on user demand. It will be appreciated that additional uses of the calculated seasonal affinity and/or seasonal theme affinity scores may be possible and are within the scope of this disclosure.

FIG. 5 is a flowchart illustrating a method 200 of calculating a seasonal affinity score and/or one or more seasonal theme affinity scores, in accordance with some embodiments. FIG. 6 illustrates a process flow 250 of the method 200 illustrated in FIG. 5 , in accordance with some embodiments. As shown in FIG. 6 , the method 200 includes two related, but separate, calculation tracks: a seasonal affinity score track 252 a and a seasonal theme affinity score track 252 b. The seasonal affinity score track 252 a is configured to calculate seasonal affinity scores for one or more seasons, as discussed in greater detail below. Similarly, the theme affinity score track 252 b is configured to calculate a theme affinity score for one or more themes associated with and/or defined for a season, as discussed in greater detail below. Each of the calculation tracks 252 a, 252 b includes the same initial step, step 202, during which historical transaction data 254 for a user is retrieved and/or received from one or more sources, such as, for example, a historical transaction database. The historical transaction data 254 may include transaction data for a specific user, such as a user associated with a user system 22 a, 22 b generating the request for a network interface. The historical transaction data 254 may include all historical transaction data for a user and/or may be limited to a specific time period. For example, in some embodiments, the historical transaction data 254 may include only the last X years of transactions for a user, although it will be appreciated that the historical transaction data 254 can include any set time period of transactions.

To calculate a seasonal affinity score, the historical data 254 is prepared and filtered at step 204 a to generate a processed data set 256. During the preparation and filter step 204 a, historical transaction data 254 may be limited (e.g., filtered) to retain only those transactions containing data relevant to a selected season. For example, in some embodiments, historical transaction data 254 may be filtered such that only transactions including items associated with a one or more specific seasons, such as, for example, a “Holiday” season are kept, while transactions including only items unrelated to the season(s) may be discarded. As one non-limiting example, historical transaction data 254 may be limited to only transactions containing items associated with the selected “Holiday” season such as “Holiday” lighting, toys, decorations, etc. Transactions that do not include at least one item associated with the selected season are discarded.

In some embodiments, historical transaction data 254 may be filtered based on a product attribute, such as a product type taxonomy, that is associated with one or more seasons. For example, the historical transaction data 254 may be filtered to retain only transactions including products having a taxonomy associated with a season, such as “Holiday decorations,” “Holiday Décor,” “Holiday Candy,” “Holiday Food,” “Holiday presents,” etc. As a specific example, the historical transaction data 254 may be filtered to retain only transactions having “Christmas” taxonomies, such as, for example, “Christmas decorations,” “Christmas décor,” “Christmas candy,” “Christmas food,” etc. Other examples may include, but are not limited to, products with specific identifiers, brands, colors, features, keywords, etc. The historical transaction data 254 may be limited such that only a transaction involving at least one product in a set of product type taxonomies is included.

In some embodiments, filtering criteria, such as a seasonal product taxonomy list 284, may be used to filter the historical transaction data 254 to generate the processed data set 256. For example, in the illustrated embodiment, a seasonal product taxonomy list 284 is received from a seasonality recommendation pipeline 282 configured to generate seasonal product index scores for each season 280 defined by the system. Defined seasons 280 may be stored in any suitable form, such as, for example, a database file or other suitable data storage mechanism. Each season 280 includes information defining the season, such as, for example, time identifiers for the calendar period corresponding to a season, theme identifiers to identify one or more themes associated with a season, product taxonomy identifiers to identify one or more product types associated with a season, keywords, etc. Each season 280 may further include information used by the seasonality recommendation pipeline 282 to select specific items for presentation to a user in a network interface, as discussed above with respect to FIGS. 3-4 . For example, in some embodiments, each season 280 includes promotions and/or modules configured to identify specific seasonal content that is presented in the network interface when a user has a high seasonal affinity score and/or seasonal theme affinity score.

In some embodiments, the seasonality recommendation pipeline 282 is configured to aggregate information from all users and/or all transactions with respect to the network interface to determine product type taxonomies, themes, etc. for each season. For example, the seasonality recommendation pipeline 282 may be configured to identify various themes and/or product taxonomies for a season defined for a set calendar period (e.g., Christmas Season defined between November 25 and December 25). In some embodiments, the seasonality recommendation pipeline 282 is configured to apply one or more processes and/or models, such as a clustering process, to identify products and themes associated with selected seasons.

In some embodiments, the historical transaction data 254 may be filtered to retain only transactions occurring during one or more specific time periods. The historical transaction data 254 may be limited to only transactions occurring during a predetermined “holiday season” that occurs during a set calendar period. For example, in some embodiments, the historical transaction data 254 may be limited to only those transactions occurring during the “Christmas season” occurring from the day after Thanksgiving (e.g., Black Friday) to some set time period after Christmas (e.g., New Year's Day). The predetermined time period may be defined on a fixed basis (e.g., a portion of a calendar year) and/or may be defined on a rolling basis (e.g., transaction data for the prior X year(s), month(s), week(s), etc.). In some embodiments, the predetermined time period is stored as part of the season 280 and provided by a seasonality pipeline 282. In some embodiments, the predetermine time period is one year.

In some embodiments, the historical transaction data 254 is converted into a form suitable for processing by a trained machine learning model, such as the trained seasonal product affinity calculation model 258 discussed below. The historical transaction data 254 may be processed to normalize or identify user data, product types, product counts, transaction counts, etc. In some embodiments, transactions having certain features under predetermine thresholds may be discarded, combined, or otherwise processed to minimize the impact of outlier transactions on the seasonal affinity score calculation. For example, in some embodiments, transactions related to specific product taxonomies may be included only where the historical transaction data 254 includes at least a threshold number of transactions including a product in a product taxonomy associated with the season, includes a number of products from specific product taxonomy, and/or any other suitable processing criteria. In some embodiments, the processed data set 256 may include a plurality of rows defining customer, product type taxonomy, and a corresponding number of transactions.

Continuing within the seasonal affinity score track 252 a, at step 206 a, the processed data set 256 is provided to a trained seasonal product affinity calculation model 258 configured to generate one or more seasonal product affinity scores 260. The trained seasonal product affinity calculation model 258 may be implemented using any suitable machine learning model, such as, for example, a collaborative filtering model. In some embodiments, the trained seasonal product affinity calculation model 258 is implemented by a trained alternating least square (ALS) model. The ALS model is a factorization model configured to alternate between solving for a first matrix, by fixing a second matrix and solving for the second matrix by fixing the first matrix. As discussed in greater detail below, the ALS model may be configured to minimize a cost function during training.

Although embodiments are discussed herein including an ALS model, it will be appreciated that any suitable model may be used to implement the trained seasonality calculation model 258. For example, and without limitation, the trained seasonality calculation model 258 may include a collaborative filtering model, a matrix factorization model, a gradient descent model, a singular value decomposition model, and/or any other suitable machine learning model.

The trained seasonal product affinity calculation model 258 is a trained machine learning model, such as an ALS model, trained using a training data set containing historical transaction data for seasonal products, for example, products including a seasonal product taxonomy, as previously discussed. The trained seasonal product affinity calculation model 258 is configured to generate an affinity score for product type taxonomies defined in the training data set. After training, the trained seasonal product affinity calculation model 258 is configured to receive historical transaction data 254, 256 corresponding to a user and determine user-specific seasonal product affinity scores 260 for one or more product type taxonomies, such as, for example, product type taxonomies associated with a season.

At step 208 a, a user-specific season affinity score 154 is determined by a combination method 262 based on combination of seasonal product type affinity scores 260 for one or more product types associated with and/or belonging to the selected season. A seasonal product taxonomy list 284 may identify the specific product taxonomies associated with a selected season. In some embodiments, the individual seasonal product type affinity scores 260 are combined with weightings or other ranking metrics to generate a user-specific season affinity score 154. In some embodiments, the individual seasonal product type affinity scores 260 are combined with seasonality index scores representing weightings or rankings of specific product taxonomies for a specific season. The seasonality index scores may be stored as part of the season definitions 280 and/or provided by a seasonality recommendation pipeline 282. The seasonal product type affinity scores 260 may be combined according to any known combinatorial method. For example, in some embodiments, the seasonal product type affinity scores 260 are combined based on weighted averages, dot products, and/or any other suitable algorithmic combinations of the calculated seasonal product type affinity scores.

FIG. 7 is a flowchart illustrating a method 300 of calculating a user-specific season affinity score 154 based on a combination of seasonal product type affinity scores 260, in accordance with some embodiments. FIG. 8 is a process flow 350 illustrating various steps of the method 300, in accordance with some embodiments. At step 302, a set of season to product type mappings 352 are received by a system, such as the affinity score calculation system 28. The set of season to product type mappings 352 identify the product taxonomies (or other product attributes) associated with one or more selected seasons. In some embodiments, the product type mappings 352 are received from the seasonality recommendation pipeline 282, although it will be appreciated that the product type mappings 352 may be stored in a separate database and/or received from a separate system.

At step 304, product type seasonality index scores 354 and user-specific product affinity scores 260 are received. The product type seasonality index scores 354 may be received from any suitable system or process, such as, for example, the seasonality recommendation pipeline 282. The user-specific seasonal product affinity scores 260 are received from the trained seasonal product affinity calculation model 258. It will be appreciated that the method 300 may be implemented as a part of the trained seasonal product affinity calculation model 258, in which case the user-specific seasonal product affinity scores 260 are passed from one internal, or hidden, layer of the trained seasonal product affinity calculation model 258 to a second internal, or hidden, layer configured to generate a user-specific season affinity score 154. In other embodiments, the method 300 may be executed separately from the trained seasonal product affinity calculation model 258 using output provided by the trained seasonal product affinity calculation model 258.

In some embodiments, the product type seasonality index scores 354 may be obtained by using one or more seasonality index and/or theme detection models. These models are configured to associate specific product types with specific themes. The models may be generated by an automated process, such as, for example, a machine learning process, and/or may be predefined models.

At step 306, the user-specific seasonal product affinity scores 260 and the seasonal product index scores 354 are combined according to a predetermined combination g(x,y) to generate a user-specific season affinity score 154. In some embodiments, calculating the user-specific seasonal affinity score 154 includes weighting each user-specific seasonal product affinity scores 260 based on a corresponding weighting provided by the seasonal product index scores 354. The weighting may be achieved using any suitable weighting mechanism and/or algorithm as is known in the art. Calculating the user-specific seasonal affinity score 154 may further include combining each of the weighted user-specific seasonal product affinity scores based on any suitable combinatorial method, such as, for example, a dot product method. In some embodiments, the trained seasonal product affinity calculation model 258 is configured to implement the combinatorial process g(x,y). In other embodiments, the combinatorial process g(x,y) may be implemented as a separate process.

With reference back to FIG. 5 , the theme affinity score track 252 b of the method 200 is discussed. The theme affinity score track 252 b is similar to the season affinity score track 252 a discussed above. To calculate a theme affinity score, the historical data 254 is processed at preparation step 204 b to generate a processed data set 290. During the preparation step 204 b, historical transaction data 254 may converted into a form suitable for processing by a trained machine learning model, such as the trained product affinity calculation model 292 discussed below. The historical transaction data 254 may be processed to normalize or identify user data, product types, product counts, transaction counts, etc. It will be noted that, unlike the seasonal affinity score track 252 a, processing of the historical transaction data 254 for use by the theme affinity score track 252 b does not include filtering. Product type filtering is omitted for the theme affinity score track 252 b to allow seasonal themes to be calculated for all potential product taxonomies identified in the set of historical transaction data 254.

At step 206 b, the processed data set 290 is provided to a trained product affinity calculation model 292. The trained product affinity calculation model 292 is configured to generate one or more user-specific product affinity scores 294, in accordance with some embodiments. The trained product affinity calculation model 292 is similar to the trained seasonal product affinity calculation model 258 discussed above. However, the trained product affinity calculation model 292 is trained on a training data set including transactions not associated with specific seasons in order to identify product affinities separate from and/or across multiple seasons. For example, a theme may include “decorations” and purchases of decorations across different seasons may each contribute to an affinity for “decoration” products within each season.

At step 208 b, user-specific seasonal theme affinity scores 156 are generated by a combination method 298 based on product taxonomy affinity scores 294 for one or more product types associated with and/or belonging to a seasonal theme included in one or more selected seasons. A seasonal theme product taxonomy list 296 may identify specific product taxonomies associated with specific seasonal themes. In some embodiments, the individual product type affinity scores 294 are combined with weightings or other ranking metrics to generate the user-specific seasonal theme affinity scores 156. In some embodiments, the individual product type affinity scores 294 are combined with product type seasonality index scores representing weightings or rankings of specific product taxonomies for a specific season or seasonal theme. The seasonality index scores may be stored as part of the season definitions 280 and/or provided by a seasonality recommendation pipeline 282. The product type affinity scores 294 may be combined according to any known combinatorial method. For example, in some embodiments, the product type affinity scores 294 are combined based on weighted averages, dot products, and/or any other suitable algorithmic combinations of the calculated seasonal product type affinity scores.

FIG. 9 is a flowchart illustrating a method 400 of calculating user-specific seasonal theme affinity scores 156 based on a combination of product type affinity scores 294, in accordance with some embodiments. FIG. 10 is a process flow 450 illustrating various steps of the method 400, in accordance with some embodiments. At step 402, a set of seasonal theme to product type mappings 452 are received by a system, such as the affinity score calculation system 28. The set of seasonal theme to product type mappings 452 identify the product taxonomies (or other product attributes) associated with one or more seasonal themes of a selected season. In some embodiments, the seasonal theme to product type mappings 452 are received from the seasonality recommendation pipeline 282, although it will be appreciated that the seasonal theme to product type mappings 452 may be stored in a separate database and/or received from a separate system.

At step 404, product type seasonality index scores 454 and user-specific product affinity scores 294 are received. The product type seasonality index scores 454 may be received from any suitable system or process, such as, for example, the seasonality recommendation pipeline 282. The user-specific product affinity scores 294 are received from the trained product affinity calculation model 292. It will be appreciated that the method 400 may be implemented as a part of the trained product affinity calculation model 292, in which case the user-specific product affinity scores 294 are passed from one internal, or hidden, layer of the trained product affinity calculation model 292 to a second internal, or hidden, layer configured to generate user-specific seasonal theme affinity scores 156. In other embodiments, the method 400 may be executed separately from the trained product affinity calculation model 292 using output provided by the trained product affinity calculation model 292.

At step 406, the user-specific product affinity scores 294 and the seasonal product index scores 454 are combined according to a predetermined combination f(x,y) to generate user-specific seasonal theme affinity scores 156. In some embodiments, calculating the user-specific seasonal theme affinity scores 156 includes weighting each user-specific product affinity scores 294 based on a corresponding weighting provided by the product seasonality index scores 454. The weighting may be achieved using any suitable weighting mechanism and/or algorithm as is known in the art. Calculating the user-specific seasonal theme affinity scores 156 may further include combining each of the weighted user-specific product affinity scores based on any suitable combinatorial method, such as, for example, a dot product method. In some embodiments, the trained product affinity calculation model 292 is configured to implement the combinatorial process f(x,y). In other embodiments, the combinatorial process f(x,y) may be implemented as a separate process.

In some embodiments, user-specific seasonal theme affinity scores 156 are generated such that the total of all of the user-specific seasonal theme affinity scores 156 for a specific season equals a predetermined total. For example, the user-specific seasonal theme affinity scores 156 for each season may be calculated as a value between 0 and 1 such that the total of the user-specific seasonal theme affinity scores is equal to 1. Similarly, the user-specific seasonal theme affinity scores 156 for each season may be calculated as a percentage value such that the total of the user-specific seasonal theme affinity scores is equal to 100%.

In some embodiments, the user-specific seasonal theme affinity scores 156 a-156 c may be time-dependent. For example, a user's preference for certain seasonal themes may increase or decrease based on timing within a season. As one non-limiting example, in some embodiments, a user may have a high seasonal affinity for a “Christmas Season.” The “Christmas Season” may include various seasonal themes, such as “Christmas Décor,” “Christmas Candies,” “Christmas Food,” etc. For a first time period within the Christmas Season, such as a period earlier in the calendar year with respect to the “Christmas Season,” a user may have a higher affinity for certain seasonal themes, such as the “Christmas Décor” theme, while having a lower affinity for certain other seasonal themes, such as the “Christmas Food” theme. As the seasons progresses, the user affinity for certain seasonal themes, such as the “Christmas Décor” theme, may decrease (representing a lower likelihood of buying themed décor as the holiday approaches) and user affinity for certain other seasonal themes, such as the “Christmas Food” theme, may increase (representing a higher likelihood of buying holiday-specific food as the holiday approaches). Changes in theme affinity over a season may be represented by using different product type seasonality index scores 454 depending on temporal input, such as, for example, based on an identification of a specific portion of a season. Time-dependent seasonal theme affinity scores may be calculated simultaneously and/or may be calculated in real-time when a user requests a user interface through the network interface system 24.

FIG. 11 is a flowchart illustrating a method 500 of training a seasonality score calculation model 258 and/or a seasonal product affinity calculation model 292, in accordance with some embodiments. FIG. 12 is a process flow 550 illustrating various steps of the method 500, in accordance with some embodiments. At step 502, a training data set 552 is received at a system configured to train a model, such as, for example, a model training system 30. The training data set 552 includes a set of labeled data configured to train an untrained model 554 according to one or more predetermined training processes. For example, in some embodiments, the set of training data 254 includes historical transaction data for a set of users over a predetermined time period, a set of seasons and seasonal parameters (e.g., time periods, seasonal themes, product type seasonal index scores, weightings, etc). The predetermined time period may be any suitable time period, such as, for example, one month, three months, six months, one year, etc.

At step 504, a machine learning process is iteratively applied to convert the untrained model 554 into a trained product affinity model 560. For example, in some embodiments, an ALS model is trained based on implicit feedback data to find product type affinities and/or preferences by minimizing a cost function 558 defined as:

${\min\limits_{x_{*},y_{*}}{\sum\limits_{u,i}{c_{ui}\left( {p_{ui} - {x_{u}^{T}y_{i}}} \right)}^{2}}} + {\lambda\left( {{\sum\limits_{u}{x_{u}}^{2}} + {\sum\limits_{i}{y_{i}}^{2}}} \right)}$

where p_(ui) is a preference for a user u to item I such that p_(ui) is 1 if the number of transactions is greater than 0 and otherwise is 0, c_(ui) is a set of variable representing and/or measuring confidence in observing p_(ui), x_(u) is the u^(th) column in a user matrix, and y_(i) is the i^(th) column in a product type matrix. Although specific embodiments are discussed herein, it will be appreciated that any suitable training method and/or cost function may be used.

At step 506, a trained model 556 is output. The trained product affinity model 560 is configured to generate either user-specific seasonal product affinity scores 260 or user-specific product affinity scores 294. The trained product affinity model 560 may include a trained seasonality scoring calculation model 258 and/or a trained seasonal product affinity calculation model 292, depending on the training data set 552 provided thereto. For example, if a training data set 552 is filtered to include season-specific product taxonomies, the training process will generate a trained seasonality scoring calculation model 258. As another example, if a training data set 552 includes general transactions without season-specific filtering, a seasonal them score calculation model 292 will be output.
